Battle.net won’t accept your phone number? Why, and what to do
In short
- Blizzard says Battle.net supports mobile and prepaid numbers, but not VoIP numbers.
- Each number can be on one Battle.net account, and it must be registered to the same country as the account.
- Overwatch 2 asks newer players to add a phone number before they can play.
Some Blizzard games ask for a phone number on your Battle.net account, and Battle.net checks the number before accepting it.
Why a number gets rejected
- It’s a VoIP number: Blizzard supports mobile plans and prepaid numbers, but not VoIP.
- It’s already on another Battle.net account.
- It isn’t registered to the same country as your Battle.net account, or the country isn’t supported.
- Your account already has a different number: check the number on your account first.
Overwatch 2
Overwatch 2 asks newer players to add a phone number to their Battle.net account. Blizzard dropped the requirement for most players with older accounts.
Match the country
Because the number must match your account’s country, use a number from the country your Battle.net account is registered in.
Using a one-time number
Whether Battle.net accepts a number is up to Blizzard; if a number from ReserveSMS gets no code within 20 minutes, the money goes back to your balance. Pick the same country as your account, and protect your sign-ins with Blizzard’s authenticator rather than this number. Get a number for Blizzard.
